In this paper, we present a new game interface design for First Person Shooters (FPS). Previously, FPS on computer is commonly played using keyboard/mouse or joystick along with PC display. We improve the communication environment between player and game world by means of new control system including large screen and laser gun, which create a real life-like space for players. Because traditional display for FPS uses CRT, it cannot support large screen display due to limitation of CRT technology. We designed and implemented a new input device using laser recognizable display. Results suggest that the combined interface creates a method which helps beginners to enjoy playing a FPS immediately and gives experienced players a new gaming experience.

In this paper, we present a new game interface design for First Person Shooters (FPS). Previously, FPSs on computer are commonly played using keyboard/mouse or joystick along with PC display. We improve the communication environment between player and game world by means of new control system including large screen, laser gun, and directional device, which create a real life-like space for players. Because traditional display for FPS uses CRT, it cannot support large screen display due to limitation of CRT technology. We designed and implemented a new input device using laser recognizable display. We implemented a new FPS based on Quake III that is in accordance with the new devices. Results suggest that the combined interface creates a method which helps beginners to enjoy playing a FPS immediately and gives experienced players a new gaming experience.

Inflatable Mouse is a volume-adjustable user interface. It can be inflated up to the volume of a familiar mouse, but be deflated and stored flat in a PC card slot of a laptop computer when not in use. Inflatable Mouse functions just like a typical mouse; moreover, it provides new interaction techniques by sensing the air pressure in the balloon of the mouse. It also addresses some issues associated with pressure-sensing interactions such as the lack of bi-directional control and the lack of effective feedback. Moreover, it can be used as both a control tool and a display tool. In this paper, the design of an Inflatable Mouse prototype is described and potential application scenarios such as zooming in/out and fast scrolling using pressure control are explained. We also discuss the potential use of Inflatable Mouse as an emotional communication tool.

There will be many large displays in common public places, and we expect that these displays will give users many convenient interactive services. However, due to the physical size, typical mouse and keyboard are not suitable for user interactions on large displays. Recently there are many studies investigating on new interaction techniques and input devices developed for user interactions in a large display. In this paper, we describe the iTILE framework designed to help develop the interactive tiled display applications. Then we describe two iTILE applications using the tape switch interface and the tangible interface with infrared camera and markers.

The speech recognition is an active research area in the human computer interface (HCI). The objective of this study is to control digital devices with voices. In addition, the mouse is used as a computer peripheral tool which is widely used and provided in graphical user interface (GUI) computing environments. In this paper, we propose a method of controlling the mouse with the real-time speech recognition function of a smartphone. The processing steps include extracting the core voice signal after receiving a proper length voice input with real time, to perform the quantization by using the learned code book after feature extracting with mel frequency cepstral coefficient (MFCC), and to finally recognize the corresponding vowel using hidden markov model (HMM). In addition a virtual mouse is operated by mapping each vowel to the mouse command. Finally, we show the various mouse operations on the desktop PC display with the implemented smartphone application.

Recombinant single chain Fv (scFv) antibodies offer many advantages over mouse monoclonal antibodies such as faster clearance from blood, improved tumor localization, reduced human anti-mouse antibody (HAMA) response, and the availability to manipulate the scFv through genetic approaches. The recombinant phage display was constructed using lym-l hybridoma cells as a source of genetic starting material. mRNA was isolated from the corresponding antibodies hybridoma cells. VH and VL cDNA were amplified with RT-PCR and linked with ScFv by linker DNA to form ScFv DNA, which then were inserted into phagemid pCANTAB5E. The phage of positive clones selected with tube containing raji lymphoma cell and infected by competent E. coli HB2151 to express soluble scFv. The scFv lym-l was secreted into the cytosol and culture supernatant and shown to be of expected size (approximately 32 kDa) by western blot. An active scFv lym-l could be produced in E. coli with soluble form and high yield from hybridoma cell line, using phage display system. Immunoreactivity indicated that scFv lym1 showed a potential biding affinity against the raji lymphoma cell as its parental antibody (intact lym-l Ab).

The most problematic part in wearable terminals is the display device. To solve these problem, the HMD(Head Mounted Display) is used to wearable terminals. It is a kind of monitor worn like glasses. However, a problem exists in HMD. To select and execute the multimedia contents, it is required to manipulate the key, button, and mouse. These actions are very uncomfortable in HMD. The most fundamental way solving these problems is to develop a new interface. In this paper, we developed the wearable image watching system based on gesture recognition system.

In this paper, we implemented a digital medical image management and a remote monitor display system for a personal computer. The designed system can display up to a 1280${\times}$1024 image which can accomodate eight images with a 256${\times}$256${\times}$8bits. When one of these images is clicked by the mouse, the selected image can be displayed with 256${\times}$256${\times}$8bits or 1024${\times}$1024${\times}$8bits. For the selected image, we can use one of the image processing functions in this system and send it to a remote monitor for the close examinations. To search and store digital images effectively, we constructed and image database management system with the B＋TREE structure. This system can be operated in an IBM-PC 386 or higher and all the function are performed easily with a mouse to provide a user firendly environment.

In ubiquitous computing, there is increasing demand for ubiquitous displays that react to a user's actions. We propose a method of navigating pictures on an ambient display using implicit interactions. The ambient display can identify the user and measure how far away they are using an RFID reader and ultrasonic sensors. When the user is a long way from the display, it acts as a digital picture and does not attract attention. When the user comes within an appropriate range for interaction, the display shows pictures that are related to the user and provides quasi-3D navigation using the TIP(tour into the picture) method. In addition, menus can be manipulated directly on a touch-screen or remotely using an air mouse. In an emergency, LEDs around the display flash to alert the user.

An experiment was designed to evaluate Fitts' law for the three-dimensional virtual pointing task and to compare the three input devices; Spaceball, Spacemouse, and 3D-Mouse. The result showed that Fitts law fitted poorly for the three-dimensional pointing tasks with relatively low coefficients of determinant. Three reasons, high degree-of-freedom, dynamic egocentric viewpoint change, and clutching problem were discussed to explain the poor fitness of Fitts' law. In terms of device comparison, the 3D-Mouse was superior to the other input devices. Also, the stereoscopic display significantly increased the performance. The results of this study can be used for the design of virtual control tasks and the selection of suitable input devices.
